Exporting Targa Sequence and Alpha Channel

I have a couple of targa sequence containing graphics that I need to export. One has an opaque arrow which rolls out over the film underneath. The second has solid text which will be laid over the arrow as it animates. I have run the image sequences in Quicktime, the arrow sequence comes out as a block of black and the solid text comes out against a black background instead of an alpha channel and I can't seem to manipulate them. I have FCP 6 which i thought had Quick Time Pro to handle alpha channels. What am I doing wrong, can anyone help?

hi carrie,

its got nothing to do with quicktime pro or not. Have you run the sequences through FCP or motion?

Hi Adam,

Thanks for this, I'll give it a go. I'm just a little confused as I used Quicktime to export a similar sequence and the opaque bits were opaque, the background transparent etc and I was then able to work with it in FCP.

Hi there,

I've tried but I can't get the animation to run as a sequence... Do you have any suggestions?

hi,

what exactly are you doing?

why are you exporting from quicktime? why dont you import the image sequence directly into motion/fcp? Not saying you;re wrong, just wondering that 's all.

Have you got the export settings correct. Not many codecs support alpha channels. Your best bet is Animation set to Millions of colours +. the + is the alpha channel.

However motion or fcp should be able to read the image files just fine.
